I booked on-line last night. Very easy. I got my e-mail confirmation from Radisson about 5 minutes later. Here's what we finally decided on:

Raiatea - Island Tour #RAI3568
Tahaa - Motu Mahana - of course!!!!
Bora Bora - 1st day - Motu and play the rest by ear
Bora Bora - 2nd day - Shark & Ray Feeding Snorkeling Tour #BRB1606
Moorea - 1st day - Dolphin Watching Expedition #MOO1798
Moorea - 2nd day - Island Drive & Belvedere #MOO1794

Notice - no waverunners. Oh well. . . .we'll be happy with the less taxing excursions. The rest who do go on that and the other more exciting ones will have to fill us in on all the fun details :)
